Question: Is the one who is overcome by vomiting during the day in Ramadhaan required to make up [the fast for that day]?

Response: This does not affect his fast and he is not required to make up [the fast for that day)] due to the saying of the Prophet (sal-Allaahu ‘alayhi wa sallam):

«Whoever is overcome by vomiting, then he is not required to make up [the fast for that day] and whoever deliberately vomits then he is required to make up [the fast for that day]», transmitted by Imaam Ahmad, Abu Daawood, at-Tirmidhee, Ibn Maajah and an-nasaa.ee with a sound chain of narration.

And with Allaah lies all the success, and may Allaah send prayers and salutations upon our Prophet Muhammad (sal-Allaahu ‘alayhi wa sallam) and his family and his companions.
